Hi,
Does the entity exists? long is initialized with 0 which may be a
valid entity in the store, and Long with null (indicating a new
object...) does not exists.

I meant try to create the actual schema (sorry for the confusion)
where the tables will be created in.
In a database a schema often corresponds with eg an user account. In
mysql the notion of a schema corresponds with a database, in oracle it
is an user. Im not sure about derby. So openjpa generat
Maybe try creating the schema before you run the application ? Schema
is not generated, so the default is used.

Is it an option to declare the id as a Long/Integer field ie of the
BigInteger? I think that will be the solution. And I don't think it is
a restriction, it is just not supported.

Did you try putting the Cascade persist and cascade merge on the
item->header relation? I think the exception means that the item is
being persisted and encounters a not persisted (managed) header. Or
try by calling persist(header) and after that the persist(item).

I have a simple case in which the version field is not updated.
1. I Create the entity
2. I change a property of the entity
3. I perform a find for the entity
All three steps are done in three seperate transactions. The version
field is updated in step 1 (from 0 to 1), as I expected. However the
v
Its the classpath, containing the required jars. Construct it using
the path element.

Hi there,
I am trying to get openjpa to generate foreign key constraints. I have
to following annotations:
... on the parent:
@OneToMany(targetEntity=Message.class, cascade=CascadeType.ALL,
mappedBy="mailingList")
private List messages = new ArrayList();
... on the child
@ManyToOn
15 matches
Mail list logo
